I have a report with one grouping. Serveral columns are formular calculated by using other columns, such as ratios. Last column is a formular of two other formular values.
Running the report shows first correct records followed by uncompleted and totally wrong records and again correct records.

In wrong records there are empty columns, columns with values from other columns, columns with parts of strings or columns with strange data, like signs ....씄䅈 䄲VI
Everyone that played a bit with c programming and pointers should know what I mean. It looks like that my report is playing monopoly with the computers memory.

Even when suppressing formular values this comes up.

I need help.
